Abstract (en)
[origin: EP1779997A2] A method of manufacturing a wind turbine rotor blade (114) includes, in one embodiment, the steps of providing a core (120), and applying at least one reinforcing skin (126) to the core to form a blade subassembly (131). Each reinforcing skin is formed from a mat of reinforcing fibers. The method also includes applying a micro-porous membrane (128) over the at least one reinforcing skin, applying a vacuum film (138) over the micro-porous membrane, introducing a polymeric resin to the core, infusing the resin through the core and through the at least one reinforcing skin by applying a vacuum to the blade assembly, and curing the resin to form the rotor blade.
